Abstract: The present invention concerns a micromotor for an indicator device comprising a hand of the type generally used in the instrument panels of motor vehicles. More specifically, the present invention concerns a micromotor of this type comprising a case wherein the thickness of one area is smaller than its maximum thickness, so as to form a free space or recess open on the exterior, in particular on the bottom of the case. This recess can be advantageously used for arranging components necessary for the operation of the instrument panel in which the micromotor is mounted, thereby saving space with respect to devices of the prior art.

Abstract: The present invention concerns a micromotor (1) for an indicator device comprising a hand (4) of the type generally used in the instrument panels of motor vehicles. More specifically, the present invention concerns a micromotor (1) of this type comprising a case wherein the thickness E2 of one area is smaller than its maximum thickness E1, so as to form a free space or recess (34) open on the exterior, in particular on the bottom (2) of the case. This recess (34) can be advantageously used for arranging components (18) necessary for the operation of the instrument panel in which the micromotor is mounted, thereby saving space with respect to devices of the prior art.
